anthers 3.5 mm. long, 1 mm. broad, lanceolate, obtuse, obtusely 

 sagittate, the thecae subequal. 



Guanai, 2000 ft., May, 1886 (no. 2562). The same as Bang's

Ruellia Lechleri Britton, sp. nov. 



Younger portions, leaf-surfaces, etc., finely short-strigose : 

 branches erect, quadrangular, dark-brown or blackish: petioles 1- 

 3 cm. long, sharply margined, dilated at the insertion : blades .5-1 

 dm. long, 1.75-3.5 cm. broad, ovate, abruptly acuminate and 

 acute at both ends, dark-green, thin, the venation prominent both 

 sides, the 8 or 10 pairs of secondaries stout, strongly ascending, 

 connected by numerous stout, straight tertiaries : flowers sessile 

 and concealed at the base among the crowded, closely appressed 

 terminal leaves : bracts foliaceous : calvx 1 . s cm. lone:, the tube cam- 

 panulate, 3 or 4 cm. long, the lobes linear-attenuate, rigid, acute :

 style about equaling the stamens, thick like the branches, which 

 are 2.5 mm. long. 



Mapiri, 5000 feet, May, 1886 (no. 1 165). Dr. Britton regards 

 it as identical with Lechler's no. 2 171 from Peru. 



Dr. Britton regards no. 1 1 18, from near La Paz, 10,000 feet (?), 

 April, 1885, as a variety or form of the same. Its flowers are a 

 fourth smaller, its calyx-lobes relatively broader, and its leaves 

 smaller.

Petioles 5 or 6 cm. long, blades reaching 1.5 cm. or more 

 long, 8 cm. broad, thinner : flower-bases less concealed by the 

 upper leaves : calyx-lobes broader: pod 1.5 cm. long, broadly 

 lance-oblong.
